ISAAC H. CONGDON, OF OMAHA, NEBRASKA.

WATER-CLOSET FUNNEL OF RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 292,472, dated January29, 1884. Application filccf July 20, sss. (No model.)

Be it known that I, ISAAC H. CONGDON, a citizen of the United States,residing at Omaha, in the county of Don glas and State of Nebraska, haveinvented certain new and useful Improvements in Water-OlosetFunnels ofRailway- Oars, of which the following is a specification, referencebeing had'therein to the accompanying drawings, in which Figure l is alongitudinal vertical section ger-car constructed according to myinvention, and the parts of the car immediately adjoining it. Fig. 2 isa vertical cross-section of a car having my improvement attachedthereto. Fig. 3 is a vertical section through my globular-shapedattachment, as shown in Fig. 1, but upon a larger scale; Fig. 4 is a topview of the attachment shown .in Fig. 3. Fig. 5 is a vertical sectionthrough the funnel at tachment shown in Fig. 2, but on a larger scale,and showing a portion of one side flattened to clear the truck. Fig; 6is a top view of the same.

My invention relates to improvements in water-closet funnels forrailway-cars, in which 7 a downdraft of air is produced therein by themotion of the car while advancing; and. the objects of my improvementare to produce a downdraft of air in the funnel, whatever may be thedirection the car is going. or whether the car is at rest and the windis blowing against it from the front, the rear or the sides. I attainthese objects by means of a globular shaped attachment affixed to thelower end of the funnel. This attachment can be made at little expense,and will produce a downdraft of air whatever may be the direction of thecurrent impinging against it, as it will induce a slight diminution ofatmospheric pressure on its leeward side, and thus induce a downwardcurrent of air through the funnel to establish an equilibrium. Any airwhich may, in passing under the lower opening of the globularattachment, be caught by the rear edge of said openingwould be guided bythe internal spherical surface, so as to form an eddy and escape againfrom the front side of the bottom opening without producing a draftupward in the funnel.

In the accompanying drawings, A represents the floor of a passenger-car,and A the ceiling under the same.

B represents the upper funnel, provided with a flange, b, resting ,uponthe floor, and carrying the seat 0, provided with a cover, 0. Incontinuation with the lower end of the funnel B is secured, by means ofa flange, 12 a funnel, B having its lower end, 12 extending slightlybelow the floor-ceiling A, and around the lower end, 12 myair-deflecting attachment is placed. It consists of ahollow globularbody, D, having its upper portion, D, cylindrical, and made to fitaround the lower end of the funnel B. This upper portion is providedwith a flange, d, having perforations d to receive screws, by which thisglobular body D is secured to the under side of the floor-ceiling,although it may also be secured to the lower end of the funnel B". .Thelower end of the body D is provided with an opening. (2 of substantiallythe same size as the cylindrical portion D thereof. The outside of thebody D being uniformly convex, will deflect downward any current of airstriking below its equator or broadest portion, whatever may be thepoints of the'compass it is coming from, and produce a correspondingdowndraft of the air in the funnel B. i

In Figs. 2, 5, and 6 a small portion of the globular body is flattenedon one side, at (2 as it may sometime be required to clear thecar-truck, but its lower edge forms acontinuation of the other sphericalsides, so that a downdraft is also produced around its lower opening.

Having now fully described my invention and its operation, what I claimis 1. In combination with the floor of a railroad-car and water-closetfunnel passing therethrough, the hollow globular body D, havingspherical sides tapering toward the'opening inthe bottomthereof,'substantially as and for the purpose described.

2. In combination with the floor of a railroad-car and the water-closetfunnel passing therethrough, the hollow globular body D, open at thebottom, and provided with a cylindrical upper portion, D, substantiallyas and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

ISAAC H. GONGDON.
